At the bottom of the picture you can see two PDA's with "Cell" on them.
Can you imagine a 4Ghz PDA? (4Ghz being the speed that the PS3 will run on).
Also, I wonder if you'll be able to play PS3 games on the PDA. Reason I say this is because the PS3 will be too fast for CD's or DVD's so they are going to use small "Cartriges" I suppose :?:
